WATER-LOCK GATE.

Specification of Letters Patent.

Patented April I l, 1908.

Application filed April 29, 1907. Serial No. 370,930.

To all whom it may concern:

Be it known that I, GOTTLIEB Loser-Inn, a citizen of the Swiss Federation, residing at Aarau, Switzerland, have invented certain new and useful Improvements in and Relating to Water-Lock Gates, of which the following is a specification.

This invention relates to water lock gates provided with an arrangement for the raising and lowering of the separate gates or fla s .without having to enterthe water or ma re use of a boat.

A method of carrying out this invention is shown in the accompanying drawings in which Figure 1 is an elevation of the lock gate with the bed in section; Fig. 2 is a plan of the left half of Fig. 1; Fig. 3 is a section in the direction of the stream; while Fig. 4 is a section on a large scale through III (Fi s. 1 and 2) of the part of the apparatus bui t in the river bed; Figs. 5 and 6 are detail views and Figs. 7 and 8 a modification of these details.

The lock arrangement shown consists of a sill a built across the stream, of wood, iron or concrete, which may rise to a greater or less extent above the bed of the river I) and on which is erected a movable wall consisting of separate gates or flaps c which may be dropped in the downward direction of the stream (Fig. 4). These movable flaps are secured by ivots d on the sill a and are maintained in their upright position against the force of the stream by the struts e.

For the purpose of lowering or raising the fla s, without having to enter the water or ma ic use of the boat, the following arrangement is provided. Somewhat above (with regard to the stream) the movable lock wall just described, an aerial line is carried across the stream, consisting of a wagon gand four runners f f f and j, for example of round or fiat iron, or preferably of wire rope. These runners (see Figs. 1, 2 and 3) are anchored at their ends and may be stretched by drums, tightening screws, or automatic arrangements as indicated at f The wagon g is hung on the runners by means of rollers and by means of a draw ro e can be moved by hand or power to, and held at, any desired osition. On the wagon are provided the winding drums h and h Close to these runners is arranged a line i consisting of a hem en rope, strong iron rod or wire rope, whici by means of a winding drum m may be let down on the river bed (position i Fig.

1) or tightened up so that it 1s raised up through its entire length to the height of the aerial line (position Fig. 1). On this line hangthe raising and lowering chains or ropes of the se arate movable flaps c of the lock wall, of w iich there are four, F, W, k and 7c, for each flap as shown in Figs. 1 and 2. These raising or lowering ropes or chains are fastened with one end on the line and the other end on the respective flaps of the lock Wall in pairs on a powerful lever 1 (Fig. 5) which is fitted close to the top edge of the flaps, so that for example, the raising ropes or chains k and k catch on the 100 s Z and Z of the lever Zin Fig. 5. If then t e line is lowered from the position '17 to the position i the raising ropes or chains sink with it on to the bed of the river and disappear under the water; if however it is wound up, which as shown in Fig. 1 can beeffected by means of the winding drum m, it lifts the chains, by means of the ends fastened thereto, u wards, so that they can be reached from t e aerial line. If now one of the flaps of the perpendicular has to be lowered, for example the third from the left (in Fig. 1), and passage allowed for the flow of the water, this is effected as follows. The line resting usually on the bed of the river is drawn upwards, thatis from the position i (Fig. 1) into the position 01 so that the raising chain ends fastened thereto may be reached from the aerial line. The wagon g is then moved until as shown in Figs. 1 and 2, it is op osite the flap to be lowered, and it is then Xed. The workmen carried on the wagon then release the outer chains, that is, k and 7c, of the flap to be moved, from the line, fasten them to the winding drums h and h and draw up these chains tightly, until the struts e (Figs. 2 and 4) as hereafter described, are automatically released. Then the chains are, by the help of the drums, slowly paid. out, and the flap c is slowly lowered on to the sill a, that is into the position 0 (Fig. 4:). If the flap is to be raised, then the two inner chains of the respective flap, that is k and k in Figs. 1 and 2, are fastened to the winding drums h and h the outer chains being left on the line. By drawing in the chains 16 and k the flap is raised and at'the same time the struts e are also raised. As soon as the flap is in the upright position the struts e take up their ori i nal position as hereinafter described. T is movable wall for any reason chains k and k the drum and fastened on the line, which latter is then again lowered on the river bed. The automatic release and lowering of the struts 6 with the flap 0 as well as the arrangement of the struts in their supporting position on the closing of the flap will now be described with respect to Figs. 5 and 6.

Close to the oint of sup ort of the strut on the flap is tted. a doub e armed lever Z (Fig. 5) on the flap 0. The outer chains 7C1 and k are then each fitted on the arm of the lever Z most remote from the said point of support, for example the chain It with the loop Z of the lever Z (Fig. 5), while the inner chains k and 7c are each connected with the arm of the lever closest to the point of su port, for example 7c with the loop Z T 1e end of the latter lever arm reaches to the point of support of the strut e.

'VVhen for the purpose of lowering the flap on the sill the outer chains is and k are wound up, these chains gradually take up the pressure exerted. by the water on the flaps and the struts are unloaded. At the same time the levers Z, since the chains k and I can give, are successively rotated into the positionshown in Fig. 5, and the struts e are released by the levers Z which bear on a roller e on the struts. The flap can now be lowered, which is effected by means of the water ressure as the chains are paid out. The ap 0 thus comes into the position a (Fig. 4) and at the same time the struts into the position e to which the latter are led by the nose pieces n, fitted on both sides of the struts, and the pivot 0.

In drawing up a flap from the osition 0 into the position 0, which is e 'ected by winding in the inner chains k and k the lever Z turns in the opposite direction so that the extension w of the strut 0 can rest upon the part 1) of the flap 0 when the strut is raised to the position 6. The strut thus falls into its original position of support in which it is secured by the noses e and e on the extension w.

In order that the guiding of the struts 6 may be assured in every position of the flaps and the struts be insured against slipping out of the guide nose pieces 77., the latter are each rovided close to their edge with a slot 1),. hese slots n serve to guide a pin 10 ar ranged between the guide nose pieces, this pin retaining the strut e in the guide nose pieces.

Figs. 7 and 8 show another method of carrying out the arrangement for the release of the strut e. The lifting parts of the flaps are here reduced to two, and. with a short flap, to one, and firmly fixed to the flap at g. The release of the struts e from their active supporting position takes place in this case by means of a special connection to the lever r, rotat mg it with the spindle s fitted on the flap 0,

can then be released from I so that the nose iece ton the spindle presses the struts out of their position of support and releases them. On lowering the connection to the lever r the nose pieces t are moved back into their former position by means of a spiral spring a acting on the spindle s and the supporting position thus left free. The arrangement described is for a greater height of lock, of for instance, about 2 meters. For smaller ones the arrangement can be sim lified; for example, with smaller heights 0' looks, flaps are sufficient with only one strut, and consequently with only one lever Z and one nosepiece 25. Also one or two runners may be used for the aerial line, while with larger apparatus still more support must be given. With a considerable width of stream intermediate supports for the aerial line may be necessary and with a good height of lock the lifting chains, which in this case become heavier, must, in order to facilitate being hauled up, be extended by lighter chains, which would then only serve for laying hold of them. The wagon 9 may be driven electrically, as shown in the drawing.
